51 NON- GAAP R E C O N C I L I AT I O N S ONEOK has disclosed in this presentation adjusted EBITDA, distributable cash flow (DCF) and dividend coverage ratio, which are non-gaap financial metrics, used to measure ONEOK s financial performance, and are defined as follows: Adjusted EBITDA is defined as net income from continuing operations adjusted for interest expense, depreciation and amortization, noncash impairment charges, income taxes, noncash compensation expense, allowance for equity funds used during construction (equity AFUDC), and other noncash items; and Distributable cash flow is defined as adjusted EBITDA, computed as described above, less interest expense, maintenance capital expenditures and equity earnings from investments, excluding noncash impairment charges, adjusted for cash distributions received from unconsolidated affiliates and certain other items; and Dividend coverage ratio is defined as ONEOK s distributable cash flow to ONEOK shareholders divided by the dividends paid for the period. These non-gaap financial measures described above are useful to investors because they are used by many companies in the industry as a measurement of financial performance and are commonly employed by financial analysts and others to evaluate our financial performance and to compare our financial performance with the performance of other companies within our industry. Adjusted EBITDA, DCF and dividend coverage ratio should not be considered in isolation or as a substitute for net income or any other measure of financial performance presented in accordance with GAAP. These non-gaap financial measures exclude some, but not all, items that affect net income. Additionally, these calculations may not be comparable with similarly titled measures of other companies. In connection with our merger transaction, we have adjusted prior periods in the following table to conform to current presentation. Furthermore, these non-gaap measures should not be viewed as indicative of the actual amount of cash that is available or that is planned to be distributed in a given period. ONEOK has also disclosed in this presentation forward-looking estimates for projected adjusted EBITDA multiples expected to be generated by announced capital-growth projects. Adjusted EBITDA multiples for the announced capital-growth projects reflect the expected adjusted EBITDA to be generated by the projects relative to the capital investment being made. A reconciliation of estimated adjusted EBITDA to GAAP net income for the announced capital-growth projects is not provided because the GAAP net income generated by the projects is not available without unreasonable efforts.
